1665: London's Last Great Plague Transcript Date: Wednesday, 30 September 2015 - 6:00PM Location: Museum of London 30 September 2015 1665: London’s Last Great Plague Professor Vanessa Harding Plague in early modern London has been the focus of many studies, but there still remain inconsistencies and puzzling elements in an apparently widely-accepted narrative. London experienced at least six epidemics of plague between 1563 and 1665, but they occurred at quite irregular intervals and their severity varied from episode to episode and from area to area. Although the quality and healthfulness of London’s built environment almost certainly deteriorated over the period, plagues did not get successively more lethal: 1665 saw the highest death-toll, but not the highest mortality in relation to population size. After 1666, plague disappeared entirely even though the metropolis continued to grow. The identification of the disease, and its association with rats and fleas, which has held sway for the last century, has come under increasingly sceptical scrutiny. So, in the 350th anniversary of what proved to be London’s last great plague year, this lecture will consider whether we really understand the epidemic any better than those who lived through it. Introduction The 350th anniversary year of the last great plague of London has not seen commemorations like those for Waterloo or Agincourt, let alone Magna Carta, but it is still a worthwhile opportunity for reflection. The story of the plague is probably very familiar to many, and there is a small library of books on the topic. The question I would like to explore tonight is, do we really understand the London plague epidemics of the 16th and 17th centuries any better than those who experienced them at first hand. I will concentrate on the plague of 1665, but the history and memory of earlier plagues are also important factors. The reason for the question is, of course, that modern understandings and indeed diagnoses of plague have changed a lot in the last thirty years. What I learned as a student is not what I now teach my own students. Partly it’s that historians’ approaches have changed – the impact and experience of plague are now foregrounded, and critically assessed – but also it is that the epidemiological consensus of the preceding century has more or less dissolved. Where once we felt confident that we knew what the disease was, and how it spread – and were able to condescend to the ignorance of our ancestors – we are now presented with a variety of possible scenarios, arguments both destructive and constructive, and some quite acerbic exchanges between their proponents. I will come back to those issues, but I want to begin with what early modern Londoners knew or believed about plague. Historic plague: contemporary knowledge The fact that early modern Londoners lacked what we would consider an adequate and accurate epidemiology of plague did not mean they were lost in a fog of ignorance, helplessly groping for information and reassurance. Londoners – and others - were quite well-informed about the appearance, progress, and even the history of the disease. They were showered with advice and instruction. The Bills of Mortality To start with there was a regular, officially-vetted, flow of information to the public, in the form of weekly handbills reporting the previous week’s deaths and causes of death. These documents were known as the Bills of Mortality; originating in the sixteenth century, they had become part of the pattern of London life by the early seventeenth. The weekly Bills were a collation of information from the 120-odd individual parishes. The clerk of each parish was responsible for collecting data from his own parish and reporting it to Parish Clerks’ Hall every Tuesday. Officials put the information from all the parishes together and made up and printed the Bills; copies went first to the Mayor and Aldermen and the Privy Council on Thursday morning, before being released for public sale. The weekly Bill was a double-sided sheet, with the week number and date at the head. The face or recto contained the information on burials and plague burials by parish, organised into groups – by 1665 these were the 97 parishes within the walls, the 16 parishes outside the walls but partly or wholly within the city’s jurisdiction, a wider circle of 10-12 parishes in Middlesex and Surrey, and a cluster of five Westminster parishes. New parishes had been added as the seventeenth century progressed, and the outer groupings somewhat reorganised, but this was the basic structure. The reverse or verso of the Bill contained a list of deaths by cause, aggregating the figures from all parishes, though sometimes leaving in some details especially for accidents; it noted how far burials had risen or fallen since the preceding week; and it also included information on the Assize of Bread, which specified the weight of a loaf of a particular price. Though comparatively few originals have survived, contemporary letters and diaries demonstrate their readership and use. The Bills were printed and distributed week in and week out, available both for an annual subscription of 4s., and for individual sale. They provided both a regular topic of conversation and subject for correspondence. John Chamberlain, frequent letter-writer of the late Elizabethan and early Stuart periods, often passed on information from the weekly bills to his correspondents; others enclosed copies with their letters. However, it was during plague epidemics that the Bills gained the largest and most avid readership. The principal justification for collecting the information was to be able to detect the onset of an epidemic – a sustained rise in weekly death totals in the early summer was a pretty good indication – so that those with responsibilities could plan their strategies. But ordinary Londoners became expert at assessing the implications of the weekly Bill, especially as it charted the spread of plague from parish to parish. Samuel Pepys first mentions reports and rumors of plague in his 1665 diary, and notes seeing houses shut up in Drury Lane, but as the epidemic progressed he clearly read the weekly bills and often notes the figures, using them to draw conclusions about the progress of the disease. The narrator of Daniel Defoe’s semi-fictional Journal of the Plague Year uses the weekly Bills to structure his story and shape its chronology, starting with the appearance of the disease in late 1664, and showing a keen awareness of the implications of numbers and geographical spread. Subsequently he includes quotations from the Bills in tabular form (indicating that Defoe, writing in 1720, had access to copies of the Bills from 1665). A complementary kind of publication – rushed into print to catch the market -was the commemorative or souvenir bill, carefully constructed typographically to catch the eye, with images or crosses, sustaining poetry or prayers, sometimes plague remedies, and weekly totals from earlier years for comparison. These were clearly published during rather than after the epidemic; one such (edged in black with a large black cross in the centre) was published on or just after 29 August 1665. Someone has carefully added in by hand the weekly totals for the rest of 1665 and well into 1666, suggesting a real interaction with the bill’s content. So the Bills provided material not just for immediate information, but also for reflection. Yearly bills were compiled from the weekly totals (in format they closely resemble the weekly bill; except that they have a more structured and synthesised account of causes of death other than plague). People who bought and studied the yearly bills, presumably published in late December or January, were not seeking fresh data of immediate import but rather the means to analyse and understand the epidemic in a more holistic way. Demographic analysis and explanation The first and greatest exponent of the bills as a source for demographic theory was Captain John Graunt, by trade a haberdasher, who in 1662 published a treatise entitled Natural and Political Observations … upon the Bills of Mortality. Graunt combined an historical perspective with a mathematical/actuarial approach to the numerical data, categorising and comparing, to demonstrate unsuspected truths and demolish myths. He aggregated and analysed the bills data to show annual mortality levels and change over time, the prevalence and cycles of various diseases and causes of death, the health of country and city. He pointed out that some causes of death varied little from year to year, while others swung widely. Of plague, ‘that greatest Disease, or Casualty of all’, he noted that there had been (at the time) four times of great mortality, of which (in his view) 1603 and 1625 were the most severe (he did not have figures for 1563, which we now think was probably the worst relative to London’s size). He argued that not all deaths due to plague were so reported, so the true figures might be 25- 30% more than the Bills indicated. He also noted that some ‘plagues’ lasted a single year, while others dragged out over several, and that deaths attributed to fevers and similar infections increased in plague years and also in the preceding year. Graunt’s book was popular and well-received; though only a modest tradesman, he was elected to the Royal Society on the strength of it. The book went into several editions (Pepys had the third edition, published by the Royal Society), and encouraged others to produce (or pirate) similar works. One of these was published as Reflections on the weekly Bills of Mortality ... which seems to be a pastiche of extracts from Graunt with the yearly bill for 1665 appended.
